检查我的 SSD 的健康状况

检查我的 SSD 的健康状况

我想检查 Ubuntu 14.04 下 SSD 的状态,因此我使用以下命令:

smartctl -a /dev/sda | grep Media_Wearout_Indicator
sudo smartctl -a /dev/sda

输出结果如下:

smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.13.0-57-generic] (local build)

我认为我必须更换固态硬盘或进行备份,对吗?
230 Life_Curve_Status231 SSD_Life_Left看起来很糟糕,我错了吗?

答案1

231 SSD_Life_Left值为 100,失败阈值为 10。

与 相同230 Life_Curve_Status。值为 100。

实际上这些参数看起来很完美。
